I have an LG laptop, only about a year old, running on Windows 7 Home Premium. It's 64-bit and on Core i3. I've recently had a problem with Windows Update, Windows Defender, and Windows Firewall - none of which are working properly. The Firewall and Defender are giving Error 0x80070424, and Windows Update says it "cannot currectly check for updates" as the service is not running. None of the three are showing up in services.msc. AVG kept notifying me of services.exe being infected but I didn't take it too seriously. Then I ran Microsoft's Anti-Malware tool and it came up with services.exe being infected with Win64/Sirefef.b. Malwarebytes came up with a Root-kit.0Access virus in the Installer files. I'm not sure what to do about this as obviously I can't delete services.exe. Also, I've had a look around the forums and apparently people are having similar issues but I can't apply that to my own problem. ** Just a note, my laptop didn't come with a Windows CD. It has an inbuilt 'Reinstall Windows' option through LG Smart Care, and also a Recovery option by LG Recovery. Any help would be appreciated! Keeping in mind that I'm not too techie but I can make my way around.
